Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13768, here are decompositions:
- 5 + 13763 = 13768
- 11 + 13757 = 13768
- 17 + 13751 = 13768
- 47 + 13721 = 13768
- 59 + 13709 = 13768
- 71 + 13697 = 13768
- 89 + 13679 = 13768
- 149 + 13619 = 13768
Showing the first eight; more decompositions exist.
